Level 48 spells on amulets

I just beat i a cheating boss and i freaked out when i goy a amulet that gives the level 48 spell REBIRTH for a level 52 then i go check how much it will sell at the bazaar it was over 10000 GOLD. And then i see if anyone already sold one of these rebirth amulets and i see a amulet that gives SCARECROW! and so there are probaly a amulet for ALL the level 48 spells.
